1. What is a Zirconia Crucible?

A Zirconia Crucible is a high-temperature ceramic container made from zirconium oxide (ZrO₂), designed for melting, heating, and processing materials in extreme environments.

2. What are Zirconia Crucibles used for?

Zirconia Crucibles are used for metal melting, ceramic processing, semiconductor research, thermal analysis, crystal growth, and laboratory high-temperature applications.

3. Why choose zirconia instead of alumina crucibles?

Zirconia offers higher fracture toughness, improved thermal shock resistance, and better resistance to cracking compared with many traditional ceramic crucible materials.

4. What temperatures can Zirconia Crucibles withstand?

Depending on grade and atmosphere, Zirconia Crucibles can operate at temperatures approaching 2,000°C.

5. Can REG Metals supply custom Zirconia Crucibles?

Yes. REG Metals provides custom sizes, shapes, machining, polishing, and fabrication services for research and industrial applications.

6. Does REG Metals provide certification?

Yes. REG Metals provides Certificate of Analysis (COA), material certifications, dimensional inspection reports, and full lot traceability.
